@Darth:
So… honest question. Why do you think that Luffy is going to be PK level BEFORE he faces Akainu, considering it goes against EVERYTHING Oda has done since Alalabasta, portraying Luffy as underdog in every major arc?
Why do you think that Akainu has no tricks left up his sleeve, or isn't in any way stronger than at Marineford?
Akainu also killed Ace. Effortlessly. In one blow. I guess that evidently doesn't count for anything, does it?
I can be wrong, but my opinion if Luffy faces Akainu before he become PK, and Akainu defeated by Luffy on that fight, we will have a new Fleet Admiral, because Akainu will resign or forced to resign. And I hope that not happen because Akainu is suit to become main brain in the last war. On MF Akainu is 53 years old … I assume on that ages Akainu is on his best form ... or 95% on his best form, but on MF Arc we not see true power that Akainu have, that why Oda not show Akainu-Aokiji fight to us. Akainu true power still mystery, but how strong he will be... still < PK.
On Ace case, Ace is not in his best form, because he was exhausted from being held in Impel Down, and Ace die because he protect Luffy. He is not ready and make his body become wall to protect Luffy. If Ace turn his body become fire and take Akainu fist he will not dies with just 2 blow.
